AUTOMOBILE BATTERY AND METHOD FOR MANUFACTURING POLE PLATES

摘要

The present invention comprises: a plurality of anode plates, formed as a mesh by forming a plurality of cuts in series on a lead plate strip rolled into a uniform thickness, for storing electricity in a chemically reactive state by means of expansion processing; a plurality of cathode plates formed as a mesh for storing electricity in a chemically reactive state; a plurality of separators disposed between the anode and cathode plates for electrical insulation, mechanical separation, and the impregnation of an AGM with electrolyte, such that the chemical reaction for storing electricity is facilitated and the pressure in the cell remains constant; upper and lower cases made of polypropylene and containing the anode plates, cathode plates, separators, and electrolyte in a plurality of mutually separate cells; and a cap coupled into the screw holes formed in the cell units in the upper case, for discharging gas generated during charging and discharging when the pressure of the gas is at or over a permissible level.
